If the velocity equals zero, the acceleration is also zero because the velocity hasn't changed, thus, the particle isn't accelerating anywhere.
This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time.
An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.
What else can I help you with?
Can an object have kinetic energy but no momentum?
Well, honey, technically speaking, yes, an object can have kinetic energy without momentum. See, momentum depends on both an object's mass and velocity, while kinetic energy only cares about velocity. So, if you have an object with mass but no velocity, it won't have momentum but can still have some kinetic energy.
Accelation due to change in direction?
Acceleration is a change in velocity with respect to time. Velocity is a vector quantity, meaning it has both a direction and a speed. Acceleration is therefore also a vector quantity. So if you change the direction an object is moving without changing its speed, you are still accelerating the object.The best example of this is circular motion. If you tie a string to a rock and swing around your head at a steady rate, the speed of the rock stays the same but its direction is continually changing. It is accelerating, and the acceleration vector points directly to the center of rotation.
Which is the smallest particle of sugar that still has all the properties of sugar?
molecule
Can you accelerate and keep the same speed?
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant
What can acceleration can be changed by?
Movement is a change in position over some time.Speed is the rate at which you move.(i.e. 40mph)Velocity is an object's speed and direction.(i.e. 40mph north)Acceleration is how much your velocity changes over some time.(i.e. 40m/sec/sec north)The equation for acceleration is (Final Velocity - Original Velocity)/Time. Imagine a vehicle starting off driving at 0 m/sec, okay? In the next second, it's traveling at 1 m/sec. In the next second, it's traveling at 2 m/sec. In the third second, it's traveling at 3 m/sec, and so on. The vehicle is accelerating because it's velocity is changing. To be even more precise, the vehicle is accelerating at a rate of 1 m/sec/sec, or 1 meter per second per second. This means that every second, the velocity changes by one second.Remember that acceleration is change in velocity over some time. So if your velocity changes, then you're accelerating. If you're moving at a constant speed, you don't really feel like your accelerating, do you? But in fact, you are. Keep in mind that if you change direction, you are also changing velocity, and so you are accelerating. Even when we are standing still on the Earth, we are accelerating relative to the sun and other heavenly bodies since the Earth is always rotating and changing direction.Acceleration doesn't always mean going faster. You can also decelerate, which you can figure is similar to slowing down. Imagine being on a roller coaster. As you dropped down a giant slope, the velocity of the coaster got faster and faster; you were accelerating. After that giant slope you get ready for another one(not the cranking kind. this slope is like a [[User:TieMyShooes|TieMyShooes]] 01:37, 25 Feb 2008 (UTC)) The coaster is decelerating up the slope because rather than getting faster in velocity, it's getting slower. However, the velocity you got from going down the previous slope gives you enough momentum to push you up the next one and so on. Whoohoo, fun!So to sum it up, acceleration can be changed by a)speed and b)direction, which we know as c)velocity. =D
Can particle with velocity or speed at zero be accelerating?
Yes, a particle can have a velocity of zero and still be accelerating if its speed is changing. Acceleration is the rate at which the velocity of an object changes over time, so even if the particle's velocity is momentarily zero, if it is changing, it is experiencing acceleration.
Can a body have no velocity and still have acceleration?
Yes, it is possible for a body to have zero velocity but still have acceleration. This occurs when the body is changing its direction of motion, even though its speed remains constant. The acceleration in this case is due to the change in direction, not speed.
Can a body have zero velocity and still acceleration?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
When the acceleration is zero what can you say about the velocity of an object?
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
Can a body have accerlation butb still have zero velocity?
Yes, it is possible. When a body thrown upward (from the surface of Earth or any other planet but with velocity small enough not to overcome the gravity) and reaches its maximum elevation its velocity is zero but the acceleration is g (due to gravity).
When average velocity is equal to its instantaneous velocity acceleration?
you are still. motion is at rest.
Can a body moving with certain velocity in the direction of east have acceleration in the direction of west?
Yes, a body moving with a constant velocity in the east direction can still have acceleration in the west direction if an external force is applied in that direction. Acceleration is the rate of change of velocity, so even if the velocity is constant, a change in direction or magnitude of the velocity can still result in acceleration.
Does an object's speed increase even if acceleration decreases?
Yes, an object's speed can still increase if its acceleration decreases, as long as the acceleration is positive. If the acceleration decreases but remains positive, the object will continue to speed up, just at a slower rate.
How an object could still be moving with the 0 acceleration?
An object can still be moving with zero acceleration if it is moving at a constant velocity. When acceleration is zero, the object's velocity remains constant, meaning it continues to move at the same speed and in the same direction without any change in speed or direction.
Can direction of velocity of a body change when its acceleration is constant?
Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.
An object with a constant acceleration but with zero velocity what is mean is n't possible.?
Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
Why does an object slow down and still have acceleration?
An object can slow down and still have acceleration if its velocity is decreasing but not necessarily reaching zero. Acceleration is a vector quantity, so it can be negative if it is in the opposite direction of the velocity. In this case, the object is still accelerating even though its speed is decreasing.
